Officials are investigating the collapse of a partially built building in Bucks County.

Wooden trusses came down on this building in Buckingham Township Thursday, pinning and injuring one worker.

Officials say the lead construction company, 4-B Construction, had a similar incident last January at a nearby site, but no one was injured.

According to OSHA's website the company does not have any recent violations.

4-B Construction has not returned our calls.
